This control file can include variables in the format "$$nnnn", which will be replaced by the current data
when the file is delivered by the web server. A list of the available variables can be found at the end of this
document.
A control file „VALUES.HTM“ with the following content:
Water temperature: $$0100 °C
Solar temperatur : $$0101 °C
Air temperature: $$0102 °C
$$0015
would upon a call to „http://xxx.xxx.xxx.xxx/values.htm“ be evaluated to:
Water temperature: 24.3 °C
Solar temperatur : 36.8 °C
Air temperature: 22.4 °C
Filtering
With such control files individual data points can also be read selectively, for example, "WTEMP.HTM" with
the content
$$0100
provides the output
24.3
To change data in the controller by the building control, the transfer of an HTML form must be simulated by
the building control system. This is done through a URL call like "http://xxx.xxx.xxx.xxx/modify?nnnn=data",
where “nnnn” is the index of the variable to be changed, and “data” represents the data to be stored.
Before the control system can change variables, it must first log in by transmitting a valid PIN number to the
variable 0003:
„http://xxx.xxx.xxx.xxx/modify?0003=dddd“, where “dddd” is the appropriate LAN-PIN for the device.
After a successful login, variables can be set, for example, target temperature set to 28 °C:
„http://xxx.xxx.xxx.xxx/modify?0110=28.3“.
Thereafter, the control should log out again by rewriting the variable 0003 with any invalid value:
„http://xxx.xxx.xxx.xxx/modify?0003=0000“
By a similar call sequence, e.g. the attractions output can be switched:
„http://xxx.xxx.xxx.xxx/modify?0003=dddd“ login
„http://xxx.xxx.xxx.xxx/modify?0017=i“ alter output state
„http://xxx.xxx.xxx.xxx/modify?0003=0000“ logout
